The neat flow copper tubes are offered bynippon tube industries. These copper tubes finds their applications in industries like refrigeration, air conditioning, transportation, electrical conductors and bus bars. Following are some of the technical features of these copper tubes: commercially pure copper is deoxidised with phosphorus in such a manner so as to leave a high residual phosphorous content which is not readily susceptible to hydrogen embrittlement; also has a good thermal conductivity. These copper tubes are best suited for soldering and brazing. However oxyacetylene welding is not recommended.
